DNS for load balancing

on our NT network

having desktop=10.20.20.1
desktop=10.20.20.2
desktop=10.20.20.3  etc

has the effect of each time a user connetcs to "desktop" they get a differnt server as per the list


but on our 2003 AD intergrated DNS  with the same records it just sticks with its first choice

any ideas why or how to fix?

thank you

Do you have an "A" record for all addresses in DNS?

You can also check your registry that round robin has not been disabled. See this article: http://www.microsoft.com/technet/prodtechnol/windowsserver2003/library/ServerHelp/e0f49958-f290-49fc-adb4-71ed8deefd62.mspx

round robin is activated, and actually appears to be working

but i have to flush the cache on the client each time to get a diffenrt ip

not really practical  anything gpo or automatic or server based to alter this?

According to Microsoft round robin should be automatic. You could configure your web serves as a NLB cluster though. This would also do load balancing.

it is automatic and it is working

my issue is the client not accepting this fact,

it works fine on NT so there must be a setting some where that tels the client to use cached infor rather than looking it up (and getting the round robin each time)

for ref

on the client

and using nslookup  it looks  fine  each time i look up "desktop2 i get the correct ip address and in a differnt order

so its deffenetly the clint doing something wrong, and the only differnce is joining the 2003 domain.
